Your arguments are compeltely nonsensical, as expected of a sanjiboy.
Jozu's defense is top tier, he is made of diamond after all, he didnt need a weapon to block that due to his DF, yet Luffy cant even block kaido's normal slashes. Yeah there is no fucking way Luffy's boundman is superior in defense compared to Jozu, not a way in hell.
Luffy couldnt even make Kaido chuckle the first tiem they fight, not to mention how inneficient he was in breaking Cracker's fucking biscuits, something Zoro wouldnt had any trouble at all. Luffy is a more balanced fighter after all, i dont deny that in terms of mobility and speed he is superior to Zoro by a lot, but the same also goes when we compare Zoro's endurance and strenght.
